I started this morning no issue, drove to work no issue, started when I left work, stopped for gas shut off the vehicle and filled up, went to get in and go home, it would crank but not start. the power door locks don't work the radio doesn't work, the windows don't work. when I turn the key the gauges barely move on the dash. when I turn the ignition to start car cranks normal but doesn't start. there has to be an electrical issue where do I start the diagnosis? help me!!!

 

I just helped by MOVING this thread to the H2 Section, where........................... that's right, all H2 questions go. Who'd a thunk? I had to look at an old post of yours to even figure out you had an H2. With every question, Year, Model, miles....

Good luck.

 

Check the grounds under the fuse panel under the hood. It seems like it would certainly be a weak ground issue.

 

I know this is a far-fetched guess, but wondering if the reason as to why the accessories do not work is that the vehicle is trying to keep enough juice to crank the car. But not enough juice for the fuel pump, so it cranks but with no fuel, no start.

First thing I would do is to swap out the battery with another vehicle. Or just jump start it form another vehicle, and see if that starts the vehicle.
Everything is pointing to this being an electrical issue.
How old is the battery?

I may be way off in my thinking, but I have see weird electrical issues on the H2. Let us know what you find. This is a very intriguing problem.
